产品介绍 
活体成像技术（optical in vivo imaging）目前主要采用生物发光（bioluminescence）与荧光（fluorescence）两种技术，生物发光法是基于萤光素酶能催化底物化学发光的原理，将体外能稳定表达萤光素酶的细胞株植入动物体内，与后期注射入体内的底物发生反应，利用光学系统检测光强度，间接反映出细胞数量的变化或细胞的定位。这项技术已被广泛应用于多个领域，最常用的有肿瘤或疾病动物模型的建立，并可用于病毒学研究、siRNA研究、干细胞研究、蛋白质相互作用研究等。
D-Luciferin是萤光素酶（Luciferase）的常用底物，普遍用于整个生物技术领域，特别是体内活体成像技术。在ATP和萤光素酶的作用下，萤光素能够被氧化，并且在560 nm检测到其化学发光。Luciferin由luc基因编码，该基因作为报告基因在多种细胞中存在。由于化学发光的低背景性，luc基因在很低的表达水平下就可以被监测到。此外，萤光素/萤光素酶被用来测量10-15摩尔量的ATP。

常见问题解答：

◆底物的激发波长和发射长？

化学发光，无需激发波长。萤火虫萤光素发射波长是 560 nm。

◆推荐仪器？多功能酶标仪能用吗？
1、推荐仪器：具有生物化学发光检测模块。萤光素产生的光可以被光度计或闪烁计数器检测。常见的活体成像仪器：如 IVIS® Lumina 小动物活体成像系统，德国 Bruker公司的 In-Vivo Xtreme 多模式小动物活体成像仪。
2、多功能酶标仪：需要和仪器厂家确认是否具体生物化学发光检测模块。注：不能用荧光显微镜。

◆底物可以进入活细胞中或者血脑屏障吗？
D-萤光素约280道尔顿，萤光素的水溶性和脂溶性都非常好，可以通过血脑屏障，胎盘屏障和血液测试屏障，也可以进入活细胞。

◆活体成像实验，无效果的原因？
成功进行活体成像实验需要以下条件：
1）目的组织或细胞表达萤光素酶基因；
2）萤光素底物注射成功；
3）依赖于发光部位的组织厚度。实验不成功，可从上述因素查找，萤光素酶基因是否表达，萤光素底物是否未正确注射，及发光部位较深等

◆产品不小心放在室温下或暴露在光线下了，还可以用吗？
产品在室温下可以稳定保存很多天，因此产品很可能仍然可以正常工作。 为安全起见，我们建议在处理大量样品或珍贵样品之前，先进行小规模阳性对照实验，以确认该产品仍然适用于您的应用。

◆两者的区别是什么？
萤光素钾盐和萤光素钠盐应用上没有差别，两者的差别在于物理性状上如外形和溶解性。钠盐的水溶性高于钾盐。从目前发表的文献来看，钾盐的使用率远高于钠盐，尤其是体内实验，两者功效相同。

◆活体成像有必要建立萤光素酶动力学曲线吗？
注射方式，动物类型以及体重等都会影响信号的发射，因此建议每次实验都要做萤光素酶动力学曲线，确定最佳信号平台期和最佳的检测时间。

生物活性

Novobiocin Sodium (Albamycin; Cathomycin) is an orally active antibiotic compound derived from Streptomyces niveus and a potent DNA gyrase inhibitor by binding the ATP-binding site in the ATPase subunit[1]. Novobiocin Sodium manifests strong anti-bacterial activities effectively against gram-positive pathogens and shows limited activity against gram-negative organisms due to LPS-containing outer membrane.Novobiocin Sodium binds to the C-terminus of Hsp90 and slightly induces degradation of Hsp90-dependent client proteins (IC50=700 µM)[1][2].

IC50 & Target

IC50: 700 μM (HSP90)[2]
体外研究
(In Vitro)

Novobiocin Sodium (0.3 mM; 48 hours) induces a caspase-3/7 enzyme–dependent apoptosis assays with an induction of approximately three- to fivefold of apoptotic cells in K562, HL60, Mutz-2[1].
Novobiocin (0-500 μM; 15-hours) is against wild type, lptB1, lptB1(R144H), and efflux pump-deficient ∆tolC strains with IC50 values of 62.5-125 μM; 0.5 μM; 62.5-125 μM; and 2 μM, respectively[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

PPTPase[1].
体外研究
(In Vitro)

In the presence of oxidizing agents vanadium ions exist as the hydrated monomer of Sodium orthovanadate (vanadate: HVO42- or H2VO4-) at micromolar concentations near neutral pH. Sodium orthovanadate (vanadate) also begins to polymerize at concentrations greater than 0.1 mM at neutral pH. The yellow-orange solutions of decavanadate can be converted to the colorless solutions of monomeric Sodium orthovanadate (vanadate) by dilution after a period of many hours. The process is hastened by boiling at pH 10, which encourages the kinetically sluggish depolymerization process[1]. Sodium orthovanadate could alter the phosphorylation status of ASK1 at serine 83 and threonine 845 induced by ischemia. Sodium orthovanadate could increase the tyrosine posphorylation of PTEN and further inhibit the activation of ASK1 via activating Akt during cerebral ischemia[2].

Non-cleavable

;

体外研究
(In Vitro)

The crosslinker Sulfo-SMCC consists of a maleimide and an N-hydroxysuccinimide ester group to bind to sulfhydryl groups and primary amines, respectively. Sulfo-SMCC inhibits the end-to-end annealing of stabilized Microtubules (MTs). MTs are treated with 250 μM Sulfo-SMCC, and imaged after incubation for 0 h, 6 h, and 24 h. MTs treated with Sulfo-SMCC shows a constant mean length, independent of the incubation time[1].

[1]

Labeled and unlabeled porcine tubulin powders are used. Sulfo-SMCC is used. MTs are polymerized to a final concentration of 2 mg/mL in 80 mM PIPES buffer (pH 6.8) containing 10 μM taxol, 2 mM MgCl2, 0.5 mM EGTA, and 1 mM GTP. A mixture of rhodamine-labeled tubulin and unlabeled tubulin (1:5) is used in the time-dependent measurements. In these experiments, polymerized MTs are divided in 2 groups: control and Sulfo-SMCC (250 μM) treated. Both samples are imaged after diluting 1:5 and incubating for 0 h (within 45 minutes after polymerization), 6 h, and 24 h[1].

生物活性

D-Luciferin (D-(-)-Luciferin) sodium is the substrate of luciferases that catalyze the production of light in bioluminescent insects[1].

体外研究
(In Vitro)

D-luciferin is the natural substrate of the enzyme luciferase (Luc), that catalyzes the production of the typical yellowgreen light of fireflies.The present review covers the synthesis of D-luciferin and derivatives or analogues that are substrates or inhibitors of the luciferase from the American firefly Photinus pyralis, the enzyme more frequently used in techniques of in vitro and optical imaging[1].
D-Luciferin exhibits a decrease in the measured Km in PC3M-Luc cell lysates with a Km of 34 μM[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究
(In Vivo)

Bioluminescence imaging (BLI) using the firefly luciferase (Fluc) as a reporter gene and D-luciferin as a substrate is currently the most widely employed technique. The total signal intensity is plotted against the time after D-luciferin injection to generate a time-intensity curve. In addition to the peak signal, the signals at fixed time points (5, 10, 15, and 20 min) after D-luciferin injection are determined as alternatives to the peak signal. The signal in a given time-intensity curve is normalized for the peak signal in the curve to represent the pattern of temporal changes after D-luciferin injection[3].
Inject with 10 μL of D-luciferin (intraperitoneally or intravenously) stock solution per gram of body weight: normally ~200 μL for a 20 g mouse for a standard 150 mg/kg injection.
Thaw D-Luciferin (either Potassium or Sodium Salt) at room temperature and dissolve in dPBS (no calcium or magnesium) to a final concentration of 15 mg/mL. Pre-wet a 0.22 μm filter by drawing through 5-10 mL of sterile H2O and discard water. Sterilize the D-Luciferin solution through the prepared 0.22 μm syringe filter.

Mice are injected with 75 mg/kg D-luciferin in 100 μL of phosphate-buffered saline subcutaneously near the scapula and were placed in the light-tight chamber of the imaging system. Beginning 5 min after injection, dorsal luminescent images with an exposure time of 1 s are acquired sequentially at a rate of one image per min until 20 min after D-luciferin injection. Data acquisition is continued until 40 min postinjection on days 3 or 5 and until 25 min on day 7, because of the prolonged time course of light emission. Binning is 4 and the field of view is 15 cm.

生物活性

Danshensu (sodium salt) is odium salt of danshensu from the widely used Chinese herb Danshen. It can inhibited phenylephrine- and CaCl2-induced vasoconstriction in Ca2+-free medium. In vitro: Sodium danshensu showed a biphasic effects on vessel tension. While low dosage of sodium danshensu produced small contraction possibly through transient enhancement of Ca2+ influx, high dosage produced significant vasodilation mainly through promoting the opening of non-selective K+ channels and small-conductance calcium-sensitive K+ channels in the vascular smooth muscle cells.[1]In vivo: Danshensu did not change the expression of AGEs but partly blocked the increased expression of RAGE in the hippocampus of diabetic mice. Danshensu could ameliorate the cognitive decline in streptozotocin-induced diabetic mice by attenuating advanced glycation end product-mediated neuroinflammation.[2]

Concentration less than 400 μM DIDS has no evident cytotoxic effect on cell viability Pre-treatment with DIDS at the concentration of 100 and 200 μM result in a prevented effect on ALA-SDT-induced cell death, while dose at 50 μM has no inhibition effect. At the concentration of 400 μM DIDS itself slightly decreases the cell viability, although there is no significant statistic difference as compared with the untreated control. Pre-treatment with DIDS (100 μM) clearly inhibit caspase-3 and caspase-9 activation[2].

Cell Assay

Cells (5×105 cells/mL) are seeded in the 35-mm Petri dishes and cultured for 72 h at 37°C. Cells are pre-incubated with ALA, and then DIDS of diverse concentrations (0-200 μM) is added before exposed to ultrasound. Cell apoptosis is detected. Briefly, seeded cells (5×105 cells/mL) are pre-treated with test compounds at the indicated concentrations for 1 h (DIDS and NAC), 1.5 h (BAPTA) or with siRNA and exposed to ultrasound. Six hours after ALA-SDT treatment, cells are collected[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
